Yeah, it just ignores all drawing beyond 400x240 on the N800. > Please note that pixeldoubler is very platform specific thing and for it > to work you have to touch the code, there's no way around it.

I don't like it as it's far too ITOS-specific (I won't be satisfied until XSP no longer exists). It'll probably be replaced with RandR some time in the future, even if the fixed resolution choices are only 800x480 and 400x240. Cheers, Daniel
